Question

In order to check the CLR function of a counter

• A. Connect the CLR input to Vcc and check to see if all of the Q outputs are HIGH
• B. Ground the CLR input and check to be sure that all of the Q outputs are LOW
• C. Apply the active level to the CLR input and check all of the Q outputs to see if they are all in their reset state
• D. Connect the CLR to its correct active level while clocking the counter; check to make sure that all of the Q outputs are toggling

Hint:

The clear (CLR) input in a counter is designed to reset the counter to its initial state irrespective of the current count.

Answer 1

The Correct Option is C

To check the CLR (clear) function of a counter, we need to apply the active level to the CLR input. When the active level is applied the counter will reset and all the outputs (Q) will go into their reset state (usually LOW). This method verifies that the CLR functionality is working correctly.
